摘　　要：利用热解法处理回收废线路板被认为是目前废线路板回收工艺中最具有前景的一项技术。其中废线路板热解后的有机高分子热解油具有潜在的利用价值。但是热解油成分比较复杂,导致了废线路板热解工艺没有得到大规模的工业化应用。通过对成分复杂的热解油进行常压实沸点蒸馏将热解油切割成不同温度段的馏分,再对不同馏分进行分析检测。分析发现,热解油各馏分主要以碳氢化合物为主,其中碳含量均在50%以上;热解油中以苯酚、4-异丙基苯酚、2-异丙基苯酚等苯酚类物质为主,含量超过60%;热解油IR检测含有CH2、CH-OH等特征峰;另外热解油中还检测出含溴苯酚类有机物,含量在10%以下。对热解油各馏分进行成分分析,为废线路板热解的机理研究及热解油的资源化利用提供基础数据和理论依据。Pyrolysis is known as a promising technique for resoure utilization of WPCB. The pyrolytic oil （PO） should be utilized according to the potential value of recycling. But it has not been applied in large-scale due to its complicated chemical composition. This paper focused on the analysis of the fractions of PO, which the frac- tions was obtained by the distillation of pyrolytic oil and analysed by elemental analyzer, GC-MS and FT-IR. The results showed that all the fractions consisted of over 50% of C and 6% of H. The phenolic compounds, which contains phenol, 4-（1-methylethyl）-phenol and 2-（1-methylethyl）-phenol, accounting for 60% of pyro- lytic oil. The spectrogram of the fractions of PO appeared characteristic peak such as CH2, CH OH. Besides, less than 10% of Br, which existed in bromophenolic compounds, was analysed in the pyrolytic oil. This works could provide theoretical basis for further research on the utilizing of all the components from pyrolysis of WPCB.
